LAM P.

SPECIFICATION forming part of Letters Patent No. 477,332, dated June 211892.. Application filed December 7, l 891. Serial No. 414,223. (Nomodel.)

To all whom it Wmy concern.-

Be it known that I, ARCHIBALD W. PAULL,

useful Improvement in Lamps, of which the following is a full, clear,and exact descrip tion, reference being had to the accompanyingdrawings, forming part of this specification, in which Figure 1 is aside elevation of the fount of my improved lamp. Fig. 2 is acentrallongitudinal section of the same. Fig. 3 is a horizontal cross-sectionalview of theburner. Figs. 4, 5, and 6 are corresponding views of a secondform of my improvement, and Fig. 7 is a detail view showing theair-spreader in place.

My invention relates to the mode of attaching the burner to the fount ofa lamp; and it consists in permanently attaching the burner to the fonntand providing a movable burnertube therein.

In the drawings, 2 represents the fount, which is set into any suitablebase. This fount is provided with the usual central drafttube 3 andburnerl. The outer casing 5 of the burner, instead of being attached bya bayonet or screw joint to the fount, as ordinarily, is permanentlyfastened thereto by soldering or other suitable means. Inside thiscasing and resting on a suitable inwardly-projecting ring or series oflugs 6 is a second movable casing 7, which is fastened to theburner-tube 8 and is removable therewith. This inner casing is providedwith suitable recesses for the chimney-holding lugs 9, so that it can betaken out from between them,and both inner and outer casings areprovided with perforations 10,those of the outer casingbeing larger thanthe inner ones. By this means the currents of air drawn in through theouter holes are divided up and turned aside by the inner perforations,and flickeringof the flame when in a draft is prevented.

In Figs. 4, 5, and 6 only a single casing 11 is provided, theburner-tube 12 being separate therefrom and when in use resting upon theannular flange 13 by a similar outwardlyturned flange 14 upon saidtube.The casing is perforated, as usual, with a series of fine holes and isprovided with the chimney-holders 15.

1G is the air-feeder, permanently held in the draft-tube by soldering orotherwise.

The advantages of my construction are obvious. In the old form inlifting the fount from the base unless the burner is securely lockedthereto the fount maybe dropped and the burning oil spread about, sincethe burner is the only projection by which the fount can be lifted, andthis accident often happens by the loosening of the joint. In myconstruction this is impossible, as the burner is permanently fastenedto the fount.

In wicking the lamp the wick-tube is lifted out, the wick placed aroundthe central tube, and the Wick-tube then replaced.

Many changes maybe made in the form and arrangementof the parts by thoseskilled in the art without departure from my invention, since What Iclaim is 1. A central-draft lamp provided with a burner, perforatedcasing permanently secured thereto, and a removable wick-tube,substantially as described.

2. A lamp-fount provided with a burner-easin g permanently securedthereto, inwardlyprojecting flanges, and a burner-tube resting upon suchflanges, substantially as described.

3. Alamp-founthavingacentraldraft-tube,a perforated burner-casingsecured to the fount, an inwardly-projecting annular flange, and aburner-tube having a projecting portion resting thereon, substantiallyas described.

4. A central-draft lamp provided with a burner having a perforatedcasing permanently attach ed thereto, and an air-feederpermanentlysecured in the draft-tube, substantially as described.

In testimony whereof I have hereunto set my hand this 30th dayofNovember,A.D. 1891.

ARCHIBALD W. PAULL.
